Subject: [ 52/89] [SCSI] isci: copy fis 0x34 response into proper buffer

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Maciej Patelczyk <maciej.patelczyk@...el.com>

commit 49bd665c5407a453736d3232ee58f2906b42e83c upstream.

SATA MICROCODE DOWNALOAD fails on isci driver. After receiving Register
Device to Host (FIS 0x34) frame Initiator resets phy.
In the frame handler routine response (FIS 0x34) was copied into wrong
buffer and upper layer did not receive any answer which resulted in
timeout and reset.
This patch corrects this bug.
